There is a lot of strange stuff in this. The OP states that he reported it to LE but does not state if a stolen vehicle report was taken. If a stolen report was taken and the location of the vehicle was known to LE they would recover/impound the vehicle, whether an arrest was made or not. My inclination was that if a report was made/taken it was not a stolen vehicle report and LE was treating it as a civil matter.

Like others, I'm having a problem grasping the exact circumstances in your situation. The police don't need to make contact with the subject to issue a warrant for his arrest, presumably for felony theft.
What are the exact circumstances of this "theft"? Was it a straight up "someone took my care and I later discovered who it was", or "I sold my car to this jerk and he hasn't paid me for it", or "I loaned my car to this guy and he hasn't returned it"?
Depending on the circumstances the event you are calling a theft may in fact be a civil dispute. I'll reserve judgement on your actions until you can give us more details.
